So I'll bite a little bit on this topic. Who says they're moving "backwards" in time? Couldn't they just be an "older" race and have developed the technology 2,000 earth years ago, but are able to zoom forward in their own concept of time to a point where there is life forms on Earth.
I don't care how developed you are as a race/population, if there is another form of life somewhere else on the universe that you've never encountered before you going to want to investigate it, if possible. Humans have dove to the depths of the ocean to study lifeforms that have never seen the light of day. While they have the ability to do things we as humans could never do to adapt to their environment, I think most scientist would consider them a subservent life form, yet they fascinate many because they're different, they survive somewhere we've never been w/o the help of a machine. Think about it, if it was discovered there was some single cell life form living on the moon just inches below the surface, how long would it take NASA to get up there and study it?
Make no mistake, if there is alternative life forms out there, self aware life forms, and they have the capability to reach us, they're going to want to study us. They may consider us insignificant to their way of life, but we're obviously significant to some way of life, no different than a single cell life form living under the surface of the moon and worthy of examination.
